Question

which have thick stems to store water and have spines instead of leaves to prevent evaporation?________​

Answer 1

Answer:

Some, like ball cacti, have shorter, more compact roots that absorb dew water that falls off the cactus. Instead of leaves, most cacti have spines or scales (which are modified leaves). These spines and scales do not lose water through evaporation (unlike regular leaves, which lose a lot of water).

Answer 2

Explanation:

Instead of leaves, most cacti have spines or scales (which are modified leaves). These spines and scales do not lose water through evaporation (unlike regular leaves, which lose a lot of water). The spines protect the cactus from predators (animals that would like to eat the cactus to obtain food and/or water).
